Major Hughes: Jennings has a plan, sir. He seems to think...
Colonel Nicholson: Yes, I'm sure Jennings has a plan. But escape? Where, into this jungle? That fellow Saito was right: no need for barbed wire or fence, one chance in a hundred of survival. I'm sure a man of Commander Shears' experience will attest to that.
Commander Shears: I'd say the odds against a successful escape are about 100 to one. But may I add another word, Colonel? The odds against survival in this camp are even worse.
